Benefits of technology

[0025]When the local information item reveals a degradation of the runway state relative to the reference runway state, data used by the system to control the braking are updated in real time during the landing, in particular either the reference runway state, or a braking data item internal to the system, which makes it possible to adjust the braking of the aircraft in keeping with the degradation suffered by the runway.
[0026]The braking performance and thus the safety of the aircraft on landing are thereby improved.

Problems solved by technology

However, the braking performance of an aircraft on a contaminated runway and thus the required stopping distance are difficult to predict on account of the difficulty of reliably and precisely knowing the runway state, which is decisive in the deceleration of the aircraft.
This runway state information, sent to the aircraft in approach phase, is however of low reliability and may become rapidly out of date.
To be precise, the runway state characteristics are highly volatile over time.
However, the runway state so determined and provided to the aircraft on approach phase does not enable such a possible runway degradation occurring between the two landings to be shown.

first embodiment

[0104]FIG. 3 represents the steps of a method for assisting the piloting of an aircraft, according to a

[0105]This method may be implemented in a system according to the invention, for example such as described with reference to FIG. 1.

[0106]During a step S310, similar to step S210 described with reference to FIG. 2, the aircraft receives a reference runway state EP.

[0107]During a step S320, similar to step S220 described with reference to FIG. 2, the assistance system for piloting 10 estimates a stopping distance prediction D(EP) based on EP and generates a braking instruction or a warning message C(EP) based on D(EP).

[0108]Step S325 consists of choosing the reference runway state EP as reference information item iref. Thus, in this embodiment iref=EP as supplied as input to the comparator 30 for the test S350.

[0109]Local measurements are then made during a step S330, as described with reference to FIG. 1 and in similar manner to step S230 of FIG. 2.

[0116]FIG. 4a represents the steps of a method for assisting the piloting of an aircraft, according to a

[0117]This method may be implemented in a system according to the invention, for example such as described with reference to FIG. 1.

[0118]During a step S410, similar to step S210 of FIG. 2 and to step S310 of FIG. 3, the aircraft receives a reference runway state EP.

[0119]During a step S420, similar to step S220 of FIG. 2 and to step S320 of FIG. 3, the system 10 for assisting piloting estimates a stopping distance prediction D(EP) based on EP and generates a braking instruction or a warning message C(EP) based on D(EP).

[0120]The braking instruction corresponds for example to the value or level of braking or deceleration operationally acceptable given the reference runway state EP.

[0121]During a step S425, the module 15 for obtaining iref determines an information item representing a critical (or theoretically attainable) level of braking or deceleration F of said aircraft deduced...

Abstract

A method and system for determining local information which is dependent on a local runway state when the aircraft is in movement on the runway in order to update, in real-time, or practically in real-time, data used by a braking assistance system, according to whether the local runway state associated with the determined local information indicates a runway deterioration relative to a reference runway state used initially.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims the benefit of the French patent application No. 1355499 filed on Jun. 13, 2013, the entire disclosures of which are incorporated herein by way of reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a method and a system for assisting the piloting of an aircraft, and to an aircraft equipped with such a system.[0003]During the phases of take-off and landing, and more generally of movement on the ground of the aircraft, knowledge of the surface state of the runway is of capital importance.[0004]Indeed, prediction of braking performance of the aircraft depends on that knowledge. It is thus possible:[0005]to estimate as best possible the distance required to stop the aircraft at the time of its landing, in the interest of safety,[0006]not to overestimate that stopping distance required to immobilize the aircraft and thus not to excessively penalize the operations of use of the runway and of the...
